Milky Way satellite galaxies

Target entity: Milky Way satellite galaxies
Context triple: [Local Group dwarf galaxies, includes, Milky Way satellite galaxies]

• A. Milky Way stellar halo
  The Milky Way stellar halo is a vast, diffuse, roughly spherical population of old, metal-poor stars and dark matter that surrounds the Milky Way’s disk and bulge, extending far into its outer regions.
• B. Milky Way globular cluster system
  The Milky Way globular cluster system is the population of ancient, densely packed star clusters that orbit the Milky Way’s halo and bulge, serving as key tracers of the galaxy’s formation and evolution.
• C. Sagittarius dwarf galaxy globular cluster system
  The Sagittarius dwarf galaxy globular cluster system is a collection of globular star clusters gravitationally bound to and associated with the Sagittarius Dwarf Spheroidal Galaxy, a satellite of the Milky Way.
• D. Milky Way–Sagittarius dwarf interaction system
  The Milky Way–Sagittarius dwarf interaction system is the ongoing gravitational encounter between our Galaxy and the Sagittarius Dwarf Spheroidal Galaxy, which is being tidally disrupted and absorbed, leaving streams of stars and clusters throughout the Milky Way halo.
• E. Milky Way dark matter halo
  The Milky Way dark matter halo is the vast, roughly spherical, invisible mass of dark matter surrounding our galaxy that dominates its gravitational potential and governs the motions of its stars, gas, and satellite galaxies.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
